Rotation: Mixed Linear/Rotational Problems

Problem #: 1 | Variant #: 1

An empty metal can rolling down a hill gets to the bottom with a speed of 4.51 m/s.
What would have been the speed if the can was full? (assume the ends of the hollow can
don't significantly affect its moment of inertia and the walls are so thin that the full
can may be considered as a solid cylinder of the same radius)

NOTE: While these problems are made by a former University Physics professor and
are seen thousands of times a week, it is possible that there are typo's or other errors that
nobody has yet reported to be fixed. If you are convinced that there is a problem with the
solution to this question please send the details to doug@dctech.com
